specification of Letters Patent. Patented June 1o, 1ere.

Application led November 13, 1918. Serial No.` 262,334.

To all whom t may concern Be it known that I, LEwIs D. TIBBETS, a citizen of the United States,re`siding at Clayton, in the county of Stevens, Stateof fash- V, ington, have invented certain new and useful lmprovements in limer Tubes for Tires; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to a tire and more particularly tothe class of inner tubes for tires used on automobiles, motorcycles or the like;

The primary object of the invention is, the provision of an inner tube of this character wherein the body thereof is made to assure maximum durability and to avoid blow-outs, punrtures or the like, the tube being possessed of the requisite resiliency and in the use thereof, will assure longevity and increased mileage;

nother object of the invention is, the provision of an inner tube of this character, wherein the construction thereof is novel in form to avoid the necessity of inflation with aiijyet it will possess the required resiliency, lightness in weight and strength.

A. further object of the invention is, the provision of an inner tube of this character, which is extremelysimple inV construction and inexpensive to manufacture.

lith these and other objects in view, the invention` consists in the features of construction, combination and arrangement of parts as will behereinafter fully described, illustrated in the accompanying drawing and pointed out in the claims hereunto appended.

In the accompanying drawing :Y

Figure l, is an elevation of an inner tube constructed lin accordance with the invention.

Fig. 2, is a fragmentary vertical longitudinal sectional view through the joined ends of the tube.

Fig. 3, is a sectional view on the line 3-3 of Fig. 2.

Fig. 4, is a fragmentary elevation showing the ends of the tube separated from each other.

Similar reference characters indicate cor-- responding parts throughout the several views in the drawing.

Referring to the drawing in detail, the 1nner-tube: comprises a tubiform body 5 of the y required size in cross sectional diameter and lis made from a plurality of strands of spring w ire 6, interwoven or laced in close crisscross relation to each other to give the appearance of braiding, so as to leavein `the nished tube practically no open space between the strips or interstices. whereby pebbles o-r other foreign matter may become embedded between the strands or work through the tube. The tube formed by the body 5 is curved to conform with the periphery of the rim of a wheel and the strands of wire possesses the requisite resistency or yieldability to render the tube flexible and resilient.

One end of the tube is formed with a contracted or reduced extremity 7 having a reinforcingband S, while the other end of the tube is of a size corresponding to the cross sectional area or diameter of the body 5 and is reinforced through the medium of a band 9 constituting a female extremity for the .reception of the contracted extremity formed by the band 8 constituting the male extremity which is adapted to fit within said female extremity which slips over the male extremity and abuts a shoulder l0 formed by the contraction of said extremity 7. These interfitted extremities 8 and 9 are brazed or welded together or otherwise permanently fastened to provide a continuous endless tube.

The reinforcing bands on the ends of the tube are engaged or fastened to the body 5, in any desirable manner to provide a unitary connection therewith.

It is of course to be understood that the circumferential size of the tube canbe varied and also the cross sectional diameter thereof corresponding to the required use of the inner tube in various sizes of tires and this tube is made by the use of suitable machinery for the weaving of the strands of the wire 6 and the finishing of the tube.

The tube has too, the advantages of the rubber pneumatic inner tube and overcomes the disadvantages of the latter.

What is claimed is:

1. An inner tube comprising a plurality of wire strands woven together to provide a tubiform body having a contracted end and an opposite end of a normal size corresponding to the cross sectional diameter of the body and adapted to be fitted over the contracted end, and reinforcements on said ends and united to each other.

2. An iner tube comprising a plurality of Wire strands Woven together to provide at tubiform body having a contracted "end find an opposite end of a normal size corresponding to the cross sectional diameter of the body and adapted to be fitted over the contracted end, mrd reinforcements 'on Said 'ends and united to each other, the contracted end of the body forming a shoulder for abutment bythe normal other end of the said body.

3. -An inner tube for tires comprising Vu tubular Woven body 'of uniform 'diameter having one end reduced at right angles to form n shoulder the other end and a` reduced portion, a bandV on the reduced 13nd,V 1-5 a'nd bztnd in th'eoth'er end engaged over the `reduced end andthe band thereon to abut Y said shoulder, said ,bands being secured'to-V gether.

In testimony whereof, YVI afx my Signature, 20
